Rockchip RK3188 is the domestic first quad-core CPU using 28nm technology, it’s also the global second quad-core mobile chip using 28mn technology after Qualcomm APQ8064.

Domestic leading 28NM technology Quad A9 architecture, performance far exceeds A7 Ultra low power consumption High speed InterChip USB interface, 4G-LTE match

The benefit of 28nm technology: Specially designed for mobile devices, offering improved battery life and greater performance. Allegedly, compared to 45nm LP SoC low-power technology, new technology improve performance 55%, save power 60%, at the same time Rockchip RK3188 using HKMG Technology ( Samsung Exynos 4412 also used this technique ), so have a good performance on anti leakage control.
 

Compare 28nm with 40nm technology, saving 20% power


A9 quad core architecture, with internal power consumption reduced, games, video, webpage browsing, data transmission power consumption is 40% lower than other A9's quad-core 40nm chipset
